LAMP.

SPECIFICATION forming part of Letters Patent No. 365,582, dated .Tune 28, 1887.

(No model.)

To all whom t may concern.-

Be it known that I, WARREN D'ARR,of Gardiner, in the county of Kennebec and State of Maine, have invented a new and useful Improvement in Lamps, of which the following is a specification. Y Y

rlihis invention relates to that class of lamps which are adapted to be llled with kerosene or other burning oil without thereby necessitating the removal of the burner.

In the accompanying drawings, in whichsimilar letters of referenceindicate like parts, Figure l is a view, part in section and part in elevation, of a lampembodying my improvement. Fig. 2 is a horizontal section on line x, Fig. l, showing the position of the parts when the lampis to be filled. Fig. 3 is a similar section showing the parts closed.

Arepresents the body of the lamp, provided -with the ordinary internally-threaded collar, a, and B is the burner, both constructed as usual.

C is a cup 0f.the shape shown, threaded at C', so as to screw into the collar a, and internally threaded at C". This cup is provided with ahorizontal perforation, D.

E is a reverse cup or shell, threaded at E', so as to screw into the cup C, and at E to receive the burner. `This cup is provided with the horizontal perforation H, and also with the flange E, to limit'its descent into the cup C.

The perforations D H are so placed relatively that when the cups C E are4 screwed tightly together they do not coincide, but are in the position shown in Fig. 3; but when the lamp is to be filled the cup E is slightly loosened or turned until the perforations coincide, as Shown in Fig. 2, when the nozzle of the oilcan may be readily inserted and the lamp filled.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination of the lamp-body A, the cup C, having its bottoni centrally perforated and provided with a short tube extending downward sufficiently to allow of an external thread, whereby said `cup may be screwed into the collar on the lamp-body, and said cup fur- .ther having its sides internally threaded, the

per edge of the cup O, and a central perforation threaded to receive the burner, and the burner B, said reverse cups O E being provided, respectively, with the horizontal perforations-D H in their sides, adapted to be made coincident or not by the relative rotation of 6o said cups, substantially as and for the purpose set forth.
